Digital-noise reduction with on-chip/module inductors

Digital-noise reduction with decoupling capacitors in ever faster lower voltage technologies is gradually rendered ineffective by the line resistance to the capacitors. In contrast, blocking inductors show excellent noise reduction in SPICE simulations, the L d I / d t self-perturbance being solved with local auxiliary capacitors. The needed values for both inductances and capacitances are small, allowing their implementation in multi-chip module (MCM), or alternative, technologies.
